other connection, the device' of this invention acting to generate steam and combine the' same with the gaseous mixture as it passes through the intake pipe into the en'- gine, the invention also providing for maintaining a certa-in predetermined water level in the water compartment of the decarbon izer. l v

With th`e above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts as herein described, illustrated and claimed.

In the acompanying drawings z-Figure 1 is a side elevation of an engine showing a decarbonizer embodying the present inven- Fig. 2 is a vertical longitudinal section through the water y chamber taken in line with the water. and

hot air inlets and outlets.

-ftional View of the heater in its relation to termined quantity of 'the engine eXha ustpipe. y mentary section through the heat collector -ing with the latter therein a Water inlet Fig 4 is a fragand, exhaust pipe.

i, Referring to the drawings 1 represent? a` Vcontainer resembling in shapey the body or bowl ot an ordinary carburetor', the said container being Vadapted to hold a prede mitted thereto through an inlet connection 2 wil ich communicates with a neck 3 located at one side of the bowl 1 and communicatand having arranged ated by the pivotally niounted arm 5 of a float v6 arranged vin the container 1 and operating to maintain a predetermined level of water in the container. The container 'is also formed with an ,emergency overfiow opening 7 so vthat in .case the inlet valve should become stuck or inoperative for any reason, the Water cannot rise any higher than the overflow opening 7.

motor boat, or in any` Fig. 3 is a sec-I water which is advalve 4l whichis actu-w ln order to heat the water inthe container l and bring the saine to a boiling point if necessary, I provide a heater 8 in the form of a tube which is closed at its extremity by a head 9, the tubular heater being for the greater portion of its length of i 21 theopposite extremit Y nectecl by a union 22 to an outlet nipple 23 uniform, diameter so that it may be slid inwardly and outwardly in relation to a stufting box l0 which is threaded as shown at 11 through an opening in lthe exhaust pipe 12 of the internal combustion engine. This permits a greater or lessV portion of the heater to be exposed Within the exhaust pipe and subjected to the direct heating action of the exhaust gases as they leave the coni'- bustion chambers of the cylinders of the engine.Y The inner end of the heater is cir larged in cylindrical form as shown at 13 and is formed with a threadedopening le in one end thereof to receive a nipple'l which is screwed into said opening and whichlcarries a tube 17 of less external diameter than the', internal diameter of the, heater, the tube 17 serving to conduct Water into the heater and discharge the same through notches or openings 18 in the extreme endthereof within the tubular body of Ythe heater. The. nipple has connected thereto by mea s-of a -union 20 a water pipe y or" which is conat the bottoml of the container 1. A return pipe 24 is connected by a nipple 25 to an elbow 26 enteringfthe side wall ot the enlarged Aportion of the heater as shown, the opposite extremity of the pipe 2t being connected by ay union 27 to a nipple 2 8 which enters the container lat a point between the top and bottom thereof and .near the normal water level in said container. By the means just described, thelwater is heated and returned to the/ container, the temperature of the'waterjbeing regulated by the extent to which the heater is exposed to the direct action-of the-burned gases in the eihaust pipe which gases impinge directly against the exposed portion of the heater.

The top of the container 1 is closed by means of a cap 29 at the top of which is a substantially horizontal "l" or tubular head 30 to one end of which is connected pipe 31 shown of the iiexible type, the other end of the pipe 31 being adapted to be connected to the air inlet of a carburetor as shown in Fig l. To the other extremity of the head aoY Q n v l 30 is attached a. pipe also preferably of` the flexible type, the pipe 32 connecting at its opposite extremity with a chambered andy substantially' semi-cylindrical he'at collector 133 which partially embraces the exhaust pipe of the engine, the heat collector being held in place by means of a strap 34 which extends around theexhaust pipe and binds the heatI collector tightly against said exhaust pipe.

'The operation of the decarbbnizer is as follows: After the engine starts its operation and the exhaustpipe becomes heated, vthe water 1n the container' 1 passes through the pipe 21 to the heater and returns from the heater through the pipe 2l to the con` tainer. The water in the container soon reaches the boiling point so 'as to give off vapor or steam. The suction of the engine draws air through the carbureter of the engine which air is supplied by the pipes 31 and 32 above described. This air is heated by the exhaust pipe and passes from the heat collector through the pi es 3l and 32 and also through the tubular 1ead30 of the container l. This heated air takes up the,

vapor or steam'in the upper portion of the water container l .and carries the same through the carbureter where it mixes with the fuel from the jet or nozzle of the carbureter and thereby furnishes the combustion chambers of the engine with a hot moist explosive mixture, materially aiding combustion and economizing in the amount of fuel oil required to obtain the maximum power and efficiency of the engine. One of the principal advantages to be derived from the decarbonizer, however, resides in the fact that Having thus described my invention, Yl claim 1. A decarbonizer for internal combustion engines, comprising a water container, a water supply connection leading thereto, means for maintaining the water at a predetermined level in said container, a water heater arranged to be. heated by the engine exhaust, pipes leading back and forth between said container and heater, and an air suction pipe leading olf from theacontainer above the -atei' level thereof and arranged to conduct the vapor from the container to the engine.

2. A decarbonizer for internal combustion engines, comprising a water container,y a

'ater supply connection leading thereto, means for maintaining the water at a predetermined level in said container, a water heatel arranged to be heated by the engine exhaust, pipes leading back and forth bctween said container and heater, and an air suction pipe. leading off from the container above the water level thereof and arranged to conduct the vapor from the container to the engine, and a heat collector for said air suction pipe associated with the engine exhaust pipe.

3. A decarbonizer for internal combustion engines, comprising a water container, a water supply connecti'on leading thereto,` means for maintaining the water at a dpredetermined level in said container, a water heater arranged to be heated by the en gine exhaust. pipes leading back and forth between said container and heater, and an air suction pipe leading oli' from the container above the water level thereof and arranged to conduct the vapor from the container to the engine, said heater being adjustable in relation to the exhaust pipe of the engine so that more or less of the heater may be exposed to the heating actionof the exhaust.
